Best Solution to Resize FAT32 Partition Without Losing Data

Updated by Daisy on Feb 22, 2023
Written by Cici

FAT32 is a file system derived from the File Allocation Table. Compared to the default NTFS file system of Windows, FAT32 has a high degree of compatibility. When you run out of space on one FAT32 partition and have plenty of room left on another, you may want to resize that FAT32 partition to use the space capacity better.

But when you are trying to resize the FAT32 partition with Disk Management, you may also encounter a problem like the following situation: 

It's a 1 TB disk with about one FAT32 partition, 730GB big. The remainder is unallocated space which I would like to add to the FAT32 partition. I just realized I couldn't extend FAT32 partitions on Windows 10 and wondered why not. - from Reddit

Don't worry. In this passage, we will help you figure out why you can't extend or shrink FAT32 on Windows and offer reliable software to help you easily resize the FAT32 partition without losing data.

Why Can't Resize FAT32 Partition in Disk Management 

When you are trying to extend the FAT32 partition or shrink the FAT32 partition in Disk Management, you may find the extend volume greyed out, and can't shrink volume.

extend and shrink volume greyed out

This is due to the limitation of the Windows built-in tool. The following reasons will lead you to be unable to resize the FAT32 partition in Disk Management:

  • The wrong file system format: Disk Management doesn't support shrinking FAT32 volume.
  • The unallocated space does not exist on the target partition's right side. 
  • The FAT32 size limit: Windows support FAT32 capacity less than or equal to 32GB.
  • There does not exist enough space to shrink the partition.

So, if you want to resize the FAT32 partition, you need to convert FAT32 to NTFS. It is a little troublesome, and you may lose data during this process. I will not recommend this solution. You can use professional third-party software – EaseUS Partition Master Free to shrink or extend the FAT32 partition without losing data.

Diskapart Command also will not support the FAT32 partition. If you use it to shrink the FAT32 partition, you will receive the error message: "You may not shrink OEM, ESP, recovery partitions, or offline volumes." So, you need to turn to EaseUS Partition Master.
